Description
Tettex 3691 Current Burden Repair
The Tettex 3691 is a current burden — a precision reference burden used when testing and calibrating current transformers, providing the defined load the CT sees during accuracy testing. As a precision standard rather than an active instrument, what matters is the stability and accuracy of its burden value, and that’s where service focuses.
June Company repairs and calibrates the Tettex 3691 for metrology labs and CT testing teams.
Common Tettex 3691 problems we fix
- Burden value out of tolerance — drift in the precision burden elements, the critical fault on a reference standard, restored and recalibrated to defined value.
- Connection/terminal faults — worn or damaged terminals affecting the burden presented, repaired.
- Switching faults on multi-value units — the selection mechanism between burden values.
- Physical or contact damage from field handling.
FAQs
My burden drifted out of tolerance — fixable? Yes. We service the burden elements and recalibrate to the defined value so your CT accuracy testing is valid again, documented with a NIST-traceable certificate.
Do you certify the burden value? Yes — verified against our reference standards with documented results.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.

Shipping & Returns
Packing your equipment. You are responsible for packaging equipment adequately for transit. We strongly recommend the original manufacturer’s case, or double-boxing with at least two inches of shock-absorbing material on all six sides. We return your equipment in the packaging it arrived in, so please send it in packaging that will survive the return trip as well. If your packaging is damaged or inadequate for the return, we will substitute suitable packaging and may charge the cost of materials.
Insurance. Equipment is not insured by June Company while in transit. We strongly recommend insuring your shipment for its full replacement value.
Risk of loss. Risk of loss remains with you until your equipment is received at our facility, and transfers back to you when your repaired unit is delivered to the carrier (F.O.B. shipping point). June Company is not responsible for equipment lost, delayed, misdelivered, or damaged in transit, in either direction.
Return label. A prepaid and preprinted return shipping label should be included with your shipment. If one is not included, we will provide one.
Transit damage. Damage occurring in transit is the responsibility of the carrier. It is not a warranty defect and is not covered by the 90-day repair warranty. Any claim must be filed by you with the carrier; we will supply photographs and documentation to support it at no charge.
